The salesman, Nick Mastraco was great...I paid $850 to get rid of a flea problem...I was guaranteed to be rid of the problem . They did come back one time but the problem continued....I talked to the owner and I was told that they would not come back out anymore..for $850 they should not have had a problem returning. I had another company come out and for $95 they got rid of the fleas...I don't recommend Bug Busters at all.
